Question

The perimeter of a rectangle is 170 cm if the length of the rectangle is 35 cm find its breadth also find the area of the rectangle.

Answer 1

Answer:

1750 sq.cm

Step-by-step explanation:

170=2(l+b)

170=2(35+x)

170=70+2x

2x=170-70

2x=100

x=100/2,x=50

x=50(x=b)

Area of rectangle =l×b

35×50=1750 sq.cm

Answer 2

Length of rectangle = 45cmPerimeter of rectangle = 170cm

2(L+B) = 170

2(45+B) =170

$45 + b = \frac{170}{2}$

45+B = 85

B = 85 – 45

B = 40cm

Area of rectangle = L ×B

= 45 × 40

= 1800 cm²
