Answer 1

Brother give one question

Answer 2

Step-by-step explanation:

1. area = lenght × breadth/width

500 = 25 × width

width = 500/25

= 25

2. it will increase

(a) increase

3. perimeter of square 4a

in this a means side

perimeter = 4a

4m = 4a

a = 4/4

a = 1

area of square is side × side

area of square = 1 × 1

= 1 sq. m

4. triangle

5. area of rectangle = length × breadth

= 15 × 6

= 90cm

6. use the formula of finding the area of triangle

which is 1/2 × base × height

so 1/2 × 6 × 9

= 3 × 9

= 27cm

7. area of llgram is base × height

8. (a) area height

9. (a) area upon base

10. (a) area of llgram

11. 1/2 × base × height

12. area upon base
