Given :- AB = 15 , BC = 20 , AD = 17 , CD = 26
Area of ∆ABC = 1/2 × B × H z
= 1/2 × 15× 20
Required Area = 150 cm²
Hypotenuse = ?
S²+S²= H²
15² + 20 ² = H²
H² = 625
H = 25
Hypotenuse = 25 cm
Area of ∆ ACD = ?
Formulae √S(s-a)(s-b)(s-d)
S = 17 + 26 + 25 /2
S = 34 cm
Now solve it according to the given eqn below
=√34(34-17)(34-25)(34-26)
= √17×17×3×3×2×2×2×2
= 204 cm²
Area of ∆ACD = 204cm²
Area of ∆ABC + ∆ACD = Area of ABCD
= 204cm²+150cm² = 354 cm²
Area of ABCD quadrilateral = 354cm²
