Question

The length of a rectangle is 10 in. What is the perimeter of the rectangle if the width is 7 in. less than the length? a. 26 in. c. 30 in. b. 13 in. d. 54 in.

Answer 1

Answer:

Option A $P=26\ in$

Step-by-step explanation:

we know that

The perimeter of the rectangle is equal to

$P=2(L+W)$

we have

$L=10\ in$

$W=L-7$ -----> equation A

substitute the value of L in the equation A

$W=10-7=3\ in$

Find the perimeter

$P=2(10+3)=26\ in$
