Question

⠀⠀⠀⠀⠀•The ratio of sides of a rectangle is 3:4 If ⠀⠀⠀⠀⠀its area is300m², find its perimeter?

Answer

⠀⠀⠀⠀⠀• Perimeter = 350m

Given

⠀⠀⠀⠀⠀• Ratio of Side = 3:4

To Calculate

⠀⠀⠀⠀⠀• Perimeter __?

Step by step explanation

Ratio of sides = 3:4

Let x be the common factor

So, Sides are 3x and 4x

Area of rectangle = l×b

➙ 300 = 3x × 4x

➙ 300 = 12x

➙ x = 300 /12

➙ x= 25

The Sides are ➙ 4x

➙ 4×25

➙ 100

3x

➙ 3×25

➙ 75

Perimeter of rectangle = 2(l+b)

putting values,

➙ 2(100+75)

➙ 2×175

➙ 350

$\bf\underline{\underline{\red{Hence:-}}}$

⠀⠀⠀⠀⠀➙ Perimeter = 350m
