Which is the best strategy to use to solve this problem?

mr. jackson wants to build a pool in his backyard. he plans to put a safety fence around the rectangular pool area that has an area of 400 square feet. he wants to use as little fence material as possible.

what are the dimensions mr. jackson should use for his rectangular pool area?

a.
make a list.

create a list of all possible whole-number combinations of length and width that would equal an area of 400 square feet. then start calculating the perimeter of each rectangle. look for a pattern to decrease the number of calculations you have to make.

b.
write a number sentence.

use a number sentence to calculate the area of a rectangle. use guess and check to find two numbers that when multiplied will give a product of 400.

c.
use objects.

arrange 400 square tiles in different patterns until you get a rectangular shape. count the number of tiles on the perimeter of the shape.

es una operación aritmética.

step-by-step explanation:

no se que fórmula requiera, pero te puedo decir que es adición. deberías revisar porque tema vas y ver que fórmulas puedes aplicar.

step-by-step explanation:

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
