Question

the shape of the top surface of the table is trapezium. Find its area if its parallel sides are 1 metre and 1.2 cm and perpendicular distance between then 0.8 m. what is the diagram of this question​

Answer 1

Answer:

hy

Step-by-step explanation:

Solution;

Given:

Perpendicular distance=.8  m

Parallel sides are 1m & 1.2 m

Area of Trapezium= ½  × (Sum of parallel sides) × Perpendicular distance

Area of Trapezium

= (1/2) × (1+1.2) ×.8

= ½× 2.2 × .8

= ½ ×1.76

=.88m²

Hence, the area of the top of the table = 0.88 m²

Answer 2

Answer: 4048 cm^2

Step-by-step explanation:

Here,

1)Given : i) Length of First =a =1m

Parallel side = 100cm

ii) Length of second

Parallel side =b = 1.2 cm

iii) Perpendicular distance=h =0.8m

between parallel sides = 80cm

Now,

We know that,

Area of Trapezium(A)= ½ × (Sum of parallel sides) × Perpendicular distance between parallel sides.

Thus,

A = ½ × (a+b) × h

= ½ × (100+1.2) × 80

= ½ ×101.2 × 80

= 40 × 101.2

= 4048 cm^2

Thus,

Area of the top surface of the table is 4048cm^2.
