Question

1)The lengthnof a rectangleis 5m greater than its breadth,and its perimeter is 250m.Find the Length and breadth

of the rectangle.​

Answer 1

Answer:

length = 65m, breadth = 60m

Step-by-step explanation:

perimeter of rectangle = 2(lenght + breadth)

length = 5 + breadth (given condition)

=> 2(l + b) = 250

=> 2((b+5) + b) = 250

=> 10 + 4b = 250

=> b = 240/4

=> b = 60

and length (l) = b+5

=> l = 65

therefore, lenght = 65m

breadth = 60m

The lengthnof a rectangleis 5m greater than its breadth,and its perimeter is 250m.Find the Length and breadth of the rectangle.

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

Given :-

Perimeter = 250

Length is 5 more than breadth

To Find :-

Length and breadth

Solution :-

We know that

Perimeter = 2(l + b)

Length = l + 5 and breadth = l

250 = 2(l + 5 + l)

250/2 = 2l + 5

125 = 2l + 5

125 - 5 = 2l

120 = 2l

120/2 = l

60 = l

Breadth = 60 m

Length = 60 + 5 = 65 m
