Answer 1

Answer:

57

Step-by-step explanation:

using formula for area of trapezium

Answer 2

Given:

base 12cm and height 6cm.

The side parallel to the given base 7cm long.

To Find:

Area of trapezium

Solution:

${ \red{\mathfrak{Formula \: Used :}}}$

${\boxed{\tt{Area \: of \: trapezium = \frac{1}{2} \times (a + b) \times h }}}$

As we have , a = 12 , ab= 7cm , h = 6cm

Let's put it in formula:

$= \: \frac{1}{2} \times (12 + 7) \times 6$

$= \: \frac{1}{2} \times 19 \times 6$

$= {\red {\tt{ 57}}}$

${ \red{ \boxed{\therefore{Area \: of \: trapezium = 57}}}}$
