(2)

GIVEN :

• breadth (b) = 100cm
• area (A) = 1250cm²

TO FIND :

• length(l)

SOLUTION:

➠Area of rectangle = 1250 cm²

➠length × breadth = 1250 cm²

➠l × 100 = 1250 cm²

➠l = $\frac{1250}{100}$

➠$\boxed{\sf{l = 12.5 cm}}$

(3)

GIVEN:

• members = 80
• clubs = 5

TO FIND :

• unit rate

SOLUTION :

➠Unit rate = $\frac{80}{5}$

➠unit rate = 16

(4)

GIVEN :

• area = 8 2/3 = 26/3
• length = 5 7/9 = 52/9

TO FIND:

• perimeter

SOLUTION:

➠Area of rectangle = 26/3

➠52/9 × breadth = 26/3

➠breadth = $\frac{26}{3} \times \frac{9}{52}$

➠breadth = $\frac{3}{2}$

➠perimeter of rectangle

➠2(l+b)

➠2($\frac{3}{2} + \frac{52}{9}$)

➠2($\frac{(3)(9) + (2)(59)}{(2)(9)}$)

➠2 ($\frac{27 +104 }{18}$)

➠2($\frac{131}{18}$)

➠$\frac{131}{9}$

(6)

➠x + 16003 = 25000

➠x = 25000 - 16003

➠$\boxed{\sf{ x = 8997 }}$
