Question

Trapezium ABCD where AB=30cm , BC=20cm , CD = 25 cm and AD= 15cm . If CE= 15cm .Find area and The perimeter

Answer 1

Answer:

Area = 412.5 cm²

Perimeter = 90 cm

Step-by-step explanation:

Area of Parallelogram = $\frac{(b1 + b2)h}{2}$

Base 1 = 30 cm (b1)

Base 2 = 25 cm (b2)

Height = 15 cm (h)

Area = $\frac{(30 + 25) 15}{2}$

        = $\frac{55 * 15}{2}$

        = $\frac{825}{2}$

        = 412.5 cm²

Perimeter = Sum of all sides

                = 30 + 20 + 25 + 15

                = 90 cm
