Question

1. the perimeter of a rectangle with a length of 10 units and a width of 5 units is: a. 25 b. 30 c. 20 d. 15

Explanation:

Step1: Recall the formula for the perimeter of a rectangle

The formula for the perimeter \(P\) of a rectangle is \(P = 2\times(\text{length}+\text{width})\).

Step2: Substitute the given values into the formula

Given length \(l = 10\) units and width \(w = 5\) units. Then \(P=2\times(10 + 5)\).

Step3: Simplify the expression

First, calculate the sum inside the parentheses: \(10+5=15\). Then \(P = 2\times15=30\).

Answer:

B. 30
