Question

The perimeter of a rectangle is 70m. If it's width three fourth of its length. Find its area.

Answer 1

Hey!

___________

Perimeter of rectangle = 70 m
Let Length = x
Breath = 3/4 x

Perimeter of rectangle = 2 (l+b)
70 = 2 ( x + 3/4x)
70 = 2 ( 4x + 3x /4)
70 = 8x + 6x/4
70 × 4 = 8 x + 6x
280 = 14x
280/14 = x

x = 20

Length = 20 m
Width = 3/4 × 20 = 15 m

Now, Area = ?
Area of rectangle = Length × Breath
= 20 × 15
= 300 m^2

___________

Hope it helps...!!!

Answer 2

Answer:

Area of rectangle = Length × Breath

= 20 × 15

= 300 m²

Step-by-step explanation:

What is a formulation of perimeter of rectangle?

Image end result for Perimeter of rectangle

What is the formulation for the fringe of a rectangle? The formulation for the fringe of a rectangle is, P = length + breadth + length + breadth. Or, P = 2(length + breadth)

The location is the area bounded with the aid of using the form of an object. The area blanketed with the aid of using the determine or any two-dimensional geometric form, in a plane, is the location of the form.

Perimeter of rectangle = 70 m

Let Length = x

Breath = 3/four x

Perimeter of rectangle = 2 (l+b)

70 = 2 ( x + 3/4x)

70 = 2 ( 4x + 3x /four)

70 = 8x + 6x/four

70 × four = eight x + 6x

280 = 14x

280/14 = x

x = 20

Length = 20 m

Width = 3/four × 20 = 15 m

Now, Area = ?

Area of rectangle = Length × Breath

= 20 × 15

= 300 m²
