Question

The perimeter of a movie screen is 70 meters it is 23 meters wide how tall is it

Answer 1

height = 12 m

Explanation:

We can assume from the problem that the movie screen is rectangular and the formula for perimeter (P) of a rectangle is

P = 2h + 2w, where l is the length and w is the width.

Thus, we can plug in 70 for P and 23 for w and solve for h:

`70=2h+(2*23)\\70=2h+46\\24=2h\\12=h`
