Question

find the diagonal of a quadrilateral whose area is 495cm×cm and whose offsets are 19cm and 11cm

Answer 1

a of Quadilateral=1/2 *diagnol*(sum of offsets)

Therefore,

495=1/2*d*(19+11)

495*2=30d

495/15=d

33=d

or

d=33cm

Answer 2

the area of a quadrilateral is = 1/2×d(sum of offset)

so

495cm²=1/2×d(19+11)cm

495cm²=1/2×d×30

495cm²=d×15

d=495/15

d=33cm
