7.2 Linear Programming 1. Petrus wants to plant x orange trees and y lemon trees.
He wants at least 3 oranges trees and at least 2 lemon trees.
(a) Write down one inequality in x and one inequality in y to
represent these conditions.
(b) There is space on his land for no more than 9 trees.
Write down an inequality in x and y to represent this
condition.

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!

by definition every angles supplementary opposite by vertex are congruent
