Arectangle has an area of 100 cm². the base of the rectangle is 25 cm. what is the height of the rectangle? a) 4 cm b)10 cm c)76 cm d)2400 cm

The answer is the option A

Step-by-step explanation:

we know that

The area of a rectangle is equal to

where

b is the base

h is the height

In this problem we have

Substitute in the formula and solve for h

Divide by both sides

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
