Question

perimeter of rectangle is 130 cm if the breadth of a rectangle is 30 cm find its length also find area of the rectangle​

Answer 1

Explanation:

p= 2(l+b)

130 = 2(X+30)

2×+60= 130

2X = 70

therefore Length =35

Answer 2

Given:

Perimeter of the rectangle = 130 cm

Breadth of the rectangle = 30

Formula:

Perimeter of rectangle = 2 (Length + Breadth)

130 = 2 (length + 30)

130/2 = length + 30

Length + 30 = 65

Length = 65 – 30

Length = 35 cm

Then:

Area of the rectangle = Length × Breadth

= 35 × 30

= 1050 cm²

Therefore:

Area of the rectangle = 1050 cm² Ans
