Question

The length of a rectangle is 10 more than its breath.if the perimeter of rectangle is 80 m. Find the length and breadth of the rectangle.​

Answer 1

Step-by-step explanation:

in this problem, 80m = side1 + side2 + side3 + side4. Now a rectangle has 2 sets of equal length sides. And we are told that the length is 10m more than it's breadth. So s1 = 15m, s2 = 15m, s3 = 25m, s4 = 25m.

The length of a rectangle is 10 more than its breath. If the perimeter of rectangle is 80m. Find the length and breadth of the rectangle.

$\huge{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$

$\sf\green{Given :}$

➣ Length of a rectangle is 10 more than its breath

➣ Perimeter of rectangle = 80m

$\sf\red{To \: Find :}$

➣ The length of the rectangle

➣ The breadth of the rectangle

$\sf\pink{Solution :}$

➪ Let, the Breadth of the rectangle = 'x' m

➪ Let, the Length of the rectangle = ( x + 10) m

➪ It is given that the perimeter of the rectangle is 80 m.

⟼ 2( l + b) = Perimeter of the rectangle

⟼ 2( x + x + 10) = 80

⟼ 2(2x + 10) = 80

⟼ 4x + 20 = 80

⟼ 4x = 80 - 20

⟼ 4x = 60

⟼ x = $\cancel\frac{60}{4}$

⟼ x = 15 m

➙ Breadth of the rectangle = x = 15 m

➙ Length of the rectangle = x + 10 = 15 + 10 = 25 m

➦ So, the length of the rectangle is 25 m and the Breadth of the rectangle is 15 m
