Question

The area of a rectangle is the product of width and length. If a rectangle has length 15m √9m and width √3m, which of the following is the area of a rectangle?

Answer 1

A. 45m^2√3
B. 45m√3m
C.135m^2√3
D.135m√3m

Answer 2

Everything is given to you.
All you need to do is multiply them.
You need to know one thing for this though...
√a * √b = √ab [understood?]
So
√8 * √6 = √8*6 = √48

So here area of the rectangle will be Length times width
= l*w
= 15√9 * √3
= 15√27
= 15*√3*3*3
= 15*3√3
= 45√3

Understood? :)

Answer 3

Is that m or meters?

If it is m then area
= 15m√9m * √3m
= 15m√27m^2
= 15m^2*3√3
= 45m^2√3

Understood? :)
