Answer:

3 : 4 = 12 : 6

2 : 5 = 30 : 75

7 : 9 = 14 : 18

8 : 3 = 64 : 24

Step-by-step explanation:

3 : 4 = 12 : ?

3/4 = 12/?

3 x ? = 12 x 4

3 x ? = 48

? = 48 ÷ 3 = 16

2 : 5 = 30 : ?

2/5 = 30/?

2 x ? = 30 x 5

2 x ? = 150

? = 150 ÷ 2

? = 75

7 : 9 = ? : 18

7/9 = ?/18

7 x 18 = ? x 9

126 = ? x 9

? = 126 ÷ 9

? = 14

8 : 3 = 64 : ?

8/3 = 64/?

8 x ? = 64 x 3

8 x ? = 192

? = 192 ÷ 8

? = 24

Find the area of the irregular figure.
Diano4ka-milaya [45]

Answer:

The area of the irregular figure is  366 cm sq.

Step-by-step explanation:

This irregular figure is made of 1 Rectangle +  1 right Triangle

<u>Area of the Rectangle:</u>

Length of the rectangle = 21 cm,

Width of the rectangle  = 14 cm

AREA of Rectangle =  LENGTH x WIDTH

          =  21 cm x 14 cm =  294 sq cm

⇒Area of the Rectangle  =   294 sq cm   ..... (1)

<u>Area of the Right Triangle:</u>

Base of the rectangle = 16 cm,

Height of the rectangle  = 21 cm -  12 cm = 9 cm

AREA of Right Triangle =  \frac{1}{2}  \times B \times H

          = \frac{1}{2} \times 16 \times 9 = 72

⇒Area of the Right Triangle   =   72 sq cm   ..... (2)

Now, area of the irregular figure  = Area of the( Rectangle  +Right Triangle)

= 294 sq cm + 72 sq cm = 366 cm sq

Hence, the area of the irregular figure is  366 cm sq.
