a) What the number is x and y?
b) Find the number x - y
c) Find the lengths of the sides

Answer 1

Answer:

Step-by-step explanation:

length = 12.5 m, breadth - 8 dm.

ANSWER:

(i) Length = 24.5 m

Breadth = 18 m

∴ Area of the rectangle = Length × Breadth

= 24.5 m × 18 m

= 441 m2

(ii) Length = 12.5 m

Breadth = 8 dm = (8 × 10) = 80 cm = 0.8 m [since 1 dm = 10 cm and 1 m = 100 cm]

∴ Area of the rectangle = Length × Breadth

= 12.5 m × 0.8 m

= 10 m
