The perimeter of reactangle is 130 cm. If the breadth of the reactangle is 30 cm, find its length. Also find the area of the reactangle

$\huge \orange{ \underline \red{ \underline \purple{Solution:}}}$

Perimeter = 2 (Length + Breadth) = 130

2 (Length + 30) = 130

Length + 30 = 65

Length = 65 − 30 = 35 cm

Area = Length × Breadth = 35 × 30 = 1050 cm².

Answer 2

Step-by-step explanation:

Perimeter = 130cm

b=30cn

2(l+b) = 130

2(l + 30) = 130

2l + 60 = 130

2l = 130-60 = 70

l = 70/2

l = 35 cm

Area = l * b

= 35* 30

= 1050 cm²
