Question

the width of a rectangle is 8 centimetres. the length of the rectangle is 50 centimetres longer than the width. what is the area, in square centimetres, of this rectangle? a. 8 b. 16 c. 66 d. 464

Explanation:

Step1: Find the length of the rectangle

The width of the rectangle is 8 cm. The length is 50 cm longer than the width, so the length $l=8 + 50=58$ cm.

Step2: Calculate the area of the rectangle

The area formula of a rectangle is $A = l\times w$. Substitute $l = 58$ cm and $w = 8$ cm into the formula, we get $A=58\times8 = 464$ square - centimeters.

Answer:

d. 464
