Question

perimeter of a rectangle is 200 metres while the difference between the length and breadth is 50 M find the area of the triangle rectangle

Answer 1

Answer:

8

Step-by-step explanation:

Perimeter = 2(length + Breadth)

200 = 2(l + b)

(l + b) = 100

Different between lenght and Breadth = 50 m

Let length be x and Breadth be x - 50

Then,

X + x - 50 = 100

2x - 50 = 100

2x = 150 m

x = 75 m

X - 50 = 75 - 50 m = 25m

Hence lenght is 75 m and Breadth is 25 m

Answer 2

perimeter =200m

length= x+50
breadth= x

perimeter of a rectangle = 2 (l+b)
=2 (x+x+50)=200
=2 (2x+50)=200
=4x+100=200
=4x=200-100
=4x=100
=x=100/4
=x=25
x+50=75

area of rectangle = length ×breadth
=25×75
=1875

hope it helps.
