Question

the area of a rectangle is 1/2 square inch. the length of the rectangle is 3/8 inch. what is the width of the rectangle?

Answer 1

Hi there,

The width would 4/3 inches. Here’s how...



a = Lw
Lw = 1/2
w = (1/2)/L

This is going to be the the rectangles square inch.

L = 3/8
This is the length.


w = (1/2)/L
w = (1/2)/(3/8)
w = (1/2)*(8/3)
w = (1/1)*(4/3)

The answer 4/3 inches.
W= 4/3 inches

Answer 2

Answer:

Step-by-step explanation:

Let's put this into the area formula. The formula for the area of a triangle is A=lw. A is area, l is length, and w is width. We already know the area, 1/2, and the length, 3/8, so let's plug that in.

1/2=3/8

Now divide 3/8 from both sides. Divide 1/2 by 3/8. When we divide fractions, you flip the fraction you are dividing by and multiply it to the original fraction. So we multiply 1/2 by 8/3.

 

1/2*8/3=8/6

Simplify 8/6.

4/3

Now we know that w=4/3, so the width is 4/3 inches.
