Answer:
Length is 90yards and width is 60yards
Step-by-step explanation:
Perimeter= 2( length+width)
let the width be x
then the length will be 30 + x
300 = 2(30+x+x)
150 = 30 + 2x
120= 2x
x = 120/2
x = 60 yards
length= 30+x
= 30 + 60
= 90yards
Green rectangle = length * width * height
3*6*2= 36
Blue rectangle
5*3*0.25 = 3.75
Pyramid = 1/3 *base^2 * height
1/3 * 16^2 * 10 = 853.33
