Question

a rectangular lawn 100 m long and 70 m broad has two crossroads running in the middle of it - one 2m wide running parallel to its length and the other 5m wide running parallel to its breadth. find the area of the lawn not covered by the crossroads. ​

Answer 1

Answer:

6460m2

Step-by-step explanation:

let the rectangular lawn be abcd

let one cross road be efgh

let second cross road be ijkl

let the common rectangle in cross roads be mnop

length of abcd- 100m

breadth of abcd -70m

area of abcd- l×b

- 100×70-7000 m2

length of efgh-2m

breadth of efgh-100m

area of efgh-l×b

-2×100-200 m2

length of ijkl-5m

breadth of ijkl- 70m

area of ijkl-l×b

- 70×5-350m2

length of mnop- 5m

breadth of mnop-2 m

area of mnop - l×b

- 5×2- 10m2

area of lawn not covered by cross roads-(area of abcd)-((area of efgh+ area of ijkl)- area of mnop)

- (7000 m2) -((200 m 2+ 350m2)-10m2)

-7000 m2 - ( 550m2 - 10m2)

-7000 m2 - 540m2

- 6460m2

thus, area of lawn not covered by cross roads is 6460m2
