Answer 2

SOLUTION

TO DETERMINE

The area and perimeter of a rectangle whose

area and perimeter of a rectangle whoselength is 50 mm and breadth is 20 mm

FORMULA TO BE IMPLEMENTED

1. Perimeter of Rectangle = 2 × ( Length + Breadth )

2. Area of Rectangle = Length × Breadth

EVALUATION

Here it is given that the length is 50 mm and breadth is 20 mm for a Rectangle

CALCULATION OF PERIMETER

Perimeter of Rectangle

$= \sf{ 2 \times ( \: Length + Breadth \: ) }$

$\sf{ = 2 \times (50 + 20) \: \: \: mm \: }$

$\sf{ = 2 \times 70 \: \: \: mm\: }$

$\sf{ = 140 \: \: mm \: }$

CALCULATION FOR AREA

Area of the Rectangle

$= \sf{ Length \times Breadth}$

$= \sf{(50 \times 20) \: \: \: \: {mm}^{2} \: }$

$\sf{ = 1000 \: \: \: {mm}^{2} \: }$
