Question

a house has rectangular yard in front of it for children to play.The lengthof rectangle exceeds its width by 6m and its perimeter is 60m, find the measurement of the yard

plz give the ans as fast as you can with explanation​

Answer 1

Hey mate!

Here is your answer:

let the width of the rectangular field be x m, then length will be (x+6)m

Now, perimeter of the field=2(length +width)

also, given that perimeter =60m

Thus, 60=2[(x+6)+x]

60/2=(x+6+x)

30=2x+6

30-6=2x

24=2x

24/2=x

12=x

Hence, width of the field is 12m and length is x+6 i.e 12+6=18m

Hope it helped ^_^

Answer 2

Perimeter of triangle is 2[l+b]=60

By solving it the length is 24 metre

Area of triangle is (l×b)=24*6=144m^2
