Question

The perimeter of a rectangle is 80x. The base is 7 times the height. In terms of x, what are the dimensions of the rectangle?
A) h = 10x, b =10x
B) H = 5x, b = 35x
C) H = 3x, b = 5x
D) h = 5x, b = 25x

Answer 1

Ithink it's b

Answer 2

The perimeter of a rectangle is given by\[P=2(b+h)\]where b is the base and h is the height. However, we also know that the base is 7 times the height or\[b=7h\]That means that\[80x=2(7h+h)\]Solve for h.

Answer 3

its b 5,35
