2️⃣ 9cm.
3️⃣ 12 cm.
4️⃣ 7.5 cm.​

Answer 1

1️⃣ 15 cm.

SOLUTION

GIVEN

The length of the rectangle is 18 cm and the area is 270 sq. cm

TO DETERMINE

The width of the rectangle

FORMULA TO BE IMPLEMENTED

Area of a rectangle = Length × Width

EVALUATION

Here it is given that length of the rectangle is 18 cm

So length = L = 18 cm

Let width = W cm

So area of the rectangle

= Length × Width

= L cm × W cm

= 18 cm × W cm

= 18W sq.cm

Now it is given that the area is 270 sq.cm

So by the given condition

18W = 270

$\displaystyle \sf{ \implies \: W = \frac{270}{18} }$

$\displaystyle \sf{ \implies \: W = 15 }⟹W=15$

FINAL ANSWER

Hence the width of the rectangle = 15 cm
