You are building a triangular garden in your backyard and want the lengths of its sides to be in the ratio 3: 4: 5. the perimeter of the garden will be 18 inches. find the lengths of the sides.

the correct answer is 5 6 and 7

a reflection across the x axis and a 90 degree rotation left and right.

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
