Answer 1

Answer:

6cm³

Step-by-step explanation:

Trapezium area formulae

Area=a+b/2*h

Therefore

a=3+3/2*3

a=6

Therefore the area of trapezium is 6cm³.

Answer 2

Answer:

First we have to find the area of triangle

area of upper triangle = 1/2 (base × height)

= 1/2 (3 × 1.5)

= 1/2 × 4.5

= 2.25 sq. cm

Now we have to find the area of rectangle

area of rectangle = length × breadth

= (3 × 1) sq. cm

= 3 sq. cm

Then we have to find the lower triangle

area of lower triangle = 1/2 (base × height)

= 1/2 (3 × 0.5)

= 1/2 × 1.5

= 0.75 sq. cm

Area of trapezium = area of upper triangle + area of rectangle + area of lower triangle = (2.25 + 3 + 0.75) sq. cm

= 6 sq. cm
