Question

find the find the area of a trapezium with base 15 cm and height 5 cm if the sides parallel to given base is 7 cm long

Answer 1

Hi friend, Harish here.

Here is your answer:

Given that,

Length of base = 15cm

Length of side parallel to base = 7cm

Height = 5cm

We know that,

$Area\ of\ trapezium= \frac{1}{2}\times height \times (sum\ of\ parallel \ sides)$

→ $= \frac{1}{2}\times 5\times (15+7)$

→ $= \frac{1}{2} \times 5 \times 22$

→$= 5\times 11$

→ $= 55 \ cm^{2}$

Therefore area of the trapezium is 55 cm².

Hope my answer is helpful to you.

Answer 2

LENGTH OF BASE - 7 CM

height - 5 cm

length of side parellel to base - 15cm

$area \: of \: trapezium \\ \\ \frac{1}{2} \times b \times h \\ \frac{1}{2} \times (15 + 7) \times 5 \\ 5 \times 11 \\ 55 {cm}^{2}$
