Question

the perimeter of rectangle is 250m . if the length of the rectangle is 5m more than twice the breath, find the length and breath of the rectangle​

Answer 1

Step-by-step explanation:

let breadth = x

ATQ length = 2x +5

perimeter of rectangle =2(L+B)

2×{2x+5+x}=250

2×{3x+5}=250

6x+10=250

6x=240

x=40m =breadth

2x+5=length

2×40+5=85m

Answer 2

Let the breadth be x.

According to the question

Length = 2×breadth+5

Length = 2x+5

We know the formula of perimeter of rectangle

= 2(length × breadth)

$→2 \times (2x + 5 + x) = 250 \\→ 2 \times (3x + 5 ) = 250 \\ →2 \times 3x + 2 \times 5 = 250 \\ →6x + 10 = 250 \\ →6x = 250 - 10 \\ →6x = 240 \\ →x = \frac{240}{6} \\ →x = 40$

breadth of rectangle = 40m

length of rectangle = 2 × 40 +5

=85m
