<u>Given</u><u>:</u>
- Base,b= 28 mm
- Perimeter,P= 74 mm
<u>To</u><u> </u><u>find</u><u> </u><u>out</u><u>:</u>
the area of a rectangle?
<u>Formula</u><u> </u><u>used</u><u>:</u>
- Perimeter of rectangle = 2(l+b)
- Area of rectangle = length × breadth
<u>Solution</u><u>:</u>
<em>We know that </em><em>,</em>
<em> </em><em> </em>Perimeter of rectangle = 2(l+b)
74= 2(l+28)
74=2l +56
2l=74-56
2l=18
length, l= 9
Now,
Area of rectangle = length × breadth
= 9 × 28
= 252 mm²
