5. Diagram 1 shows an isosceles triangle with a base of 4y cm and a height of (y + 5) cm. Diagram 2 shows a square with sides of y cm.
The area of the triangle is more than the area of the square by 39 cm². Calculate the difference
in perimeter between both shapes.

Height of the triangle = y + 5 cm
Length of base = 4y cm
Height of the square = y cm

step-by-step explanation:

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75

prime
