Solution
Similar question the area of the trapnizium is 210cm2..and its hength is 5m if one of the parallel sides is longer than the other by 8cm find the two parallel
area of trapazium = h/2 * (a+b)
let one side is x & another is x +8
5/2*(x+x+8)=210
2.5*(2x+8) =210
5x+20=210
5x=190
x=38
one side is 38 & another is 38+8=46 cm
hope now u do it
