14) Find the area of A whose base is 3 cm and height is 4 cm.
15) Find the area of parallelogram whose base 7 cm and
height 4 cm.
16) Find the area of a circle whose diameter is 49m.
(1x454)
17) Fill in the blanks:
1) 369 = = 369
2) A triangle has vertices.
3) Formula for simple interest is,
4) Formula for area of Rectangle is,​

Answer 1

Answer:

14).

Step-by-step explanation:

Area of the triangle = 1 / 2 × base × height

= 1/2 × 3 × 4 = 6 cm sq.

15). Area of parallelogram = 1/2 × base × height

= 1/2 × 7 × 4 = 14 cm sq.

16).

area of circle = 2πr

diameter = 49 m

then, radius = 49/2

So, 2 × 22/7 × 49/2 = 154 m sq.

17).

1). we not know what you are say .

2). three vertices.

3). p× r × t / 100

where , p= principal .

r = rate

t = time

4). l × b

where,

l = length

b = breadth.

I hope you it's helpful for all of you.
