Question

The length of a rectangle is 3 times it’s width. The rectangles width is 4m. What is the area of the rectangle

Answer 1

48 m²

Explanation:

A rectangle has width and length as dimension.

The rectangles width is 4 m

The length of a rectangle is 3 times it’s width.

Therefore, Length = 3w

Length = 3(4)

= 12 m

L = 12 and w = 4

Area of rectangle = L x W

= 12 x 4

= 48 m²

Hence, The area of rectangle is 48 m²

Answer 2

Length (L): 3w ⇒3(4) = 12

width (w): w ⇒ 4

Area (A) = L x w

A = 12 x 4

A = 48

Answer: 48 m²
