A house cast 65-foot shadow. A person standing nearby cast 7.2 foot shadow. Their height is 4.8 feet. What is the height of the house?

42.43 feets

Step-by-step explanation:

Given :

(Height of house / shadow of house) = (height of person / shadow of person)

(height of house / 65) = (4.8 / 7.2)

Cross multiply

Height of house * 7.2 = 4.7 * 65

Height of house = 305.5 / 7.2

Height of house = 42.43 feets

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
