Question

find the area of a field in the shape of rhombus having each side equal to 13m and one of its diagonal is 24m​

Answer 1

ar triangleABC

by using herons formula

s=24+13+13/2

= 50/2

=25

arABC=

$\sqrt{25(25 - 13)(25 - 13)(25 - 24)}$

$\sqrt{25 \times 12 \times 12 \times 1}$

$\sqrt{5 \times 5 \times 5 \times 5 \times 2 \times 2 \times 3 \times 2 \times 2 \times 3}$

5×5×2×3×2

=300 cm^2

ArADC=300 cm^2

total area=600 cm^2
