Answer 1

Heya mate!!

Rhombus AREA FORMULA IS

$\frac{1}{2} \times d \times d$

$\frac{1}{2} \times 12 \times 16 = 96 {cm}^{2}$

Area of 300 Rhombus = 96×300=28800 cm^2

Area of Trapezium =

$\frac{1}{2} \times 22 \times 10$

$110 {cm}^{2}$

Area of 11 Trapezium

$110 \times 100 = 11000 {cm}^{2}$

$total \: area = 11000 + 28800 = 39800cm2$

$1m = 100cm \\ 1cm = \frac{1}{100} m \\ 3.98 {m}^{2}$

$cost = 3.98 \times 240 = 955.2$

Hope it helps u dear✌️✌️
