Question

please answer me of all questions please

please answer me fastest and explain it in process and don't send rabish answer plzzzzzz ​

Answer 1

Answer:

200*75 = 15000 m^2

100 * x = 15000 m^2

x = 15000/100

x = 150m

Step-by-step explanation:

Answer 2

Answer:

9. 150 m

10. 200 m

11. 103 cm²

Step-by-step explanation:

9. According to question both plots have same area,

Area of first plot=(l*b)=(200*75)=15000m²

Let the second plot's length be x,

Then,

15000=(x*100)

It implies that,

x=(15000/100)= 150m (Answer)

10. Side of square plot=220m

So, area if square plot=220*220= 48400m²

According to question both plots have same area,

So, let the width of rectangular plot be x,

Then,

48400=(242*x)

It implies that,

x=(48400/242)=200 m

11. Please refer to the diagram above,

We'll find the areas one by one,

Area of A=(5*1)=5 cm²

Area of B=[(8-1)*5]=(7*5)=35 cm²

Area if C=[(10-5)*(8-1)]=(5*7)=35 cm²

Area of D=(6*4)=24 cm²

Area of E=(2*2)=4 cm²

Therefore,

Total area of figure= 5+35+35+24+4=103 cm²
