Chapter 3: Q. 410 (page 409)

The width of a rectangle is $45$ centimeters. The area is $2, 700$ square centimeters. What is the length?

Short Answer

Expert verified

The length of the rectangle is $60 c m$ .

Step by step solution

Step 1. Given information.

Consider the given question,

Area of the given rectangle is $2700$ square centimeters.

Width of the given rectangle is $45$ centimeters.

Step 2. Find the length.

We know the formula of the area of the rectangle is given below,

$A = l e n g t h \times w i d t h . . . . . . (i)$

Substitute the given values in equation (i),

$2700 = l e n g t h \times 45 l e n g t h = \frac{2700}{45} l e n g t h = 60 c m$

Step 3. Check the answer.

Substitute the values of length and width in equation (i),

$A = 60 \times 45 A = 2700 c m^{2}$

Hence, the value of the length obtained is correct.
