Question

Show how we can use Fig. (1) to find the area of Fig. (2). Also find the perimeter of each
figure​

Answer 1

Answer:

Step-by-step explanation:

the fig 1 is trapezium and in fig 2 there are 2 trapezium with same measure as trapped in fig1

so area of trapezium=h X sum of parallel sides/2

=4 X (11+5)/2

=4X16/2

=64/2

=32cm²

so area of fig 2=2 X 32

=64cm²

perimeter of fig 1=11+(5 X 3)

=11+15

=26cm

perimeter of fig 2=6 X 5

=30cm

hope u understand the answer

if you have any further doubts u can message me

Answer 2

Step-by-step explanation:

1. We know that in fig 1 the height is 4 cm ,parallel side 11 and 5
2. Formula of trapezium = 1/2+sum of parallel sides *height
3. 1/2+(11+5)*4= 32cm^2
4. There are two trapezium in fig 2 so,32*2=64cm^2
5. area of fig 2 is 64cm^2
