Question

pls help me in this​

Answer 1

Step-by-step explanation:

You can find out the bases and heights with this formula-

Area of a triangle = 1/2 ×base×height

For example in the first sum,

Area=20cm^2

Height=5cm

Let base be b

A=1/×b×h

20=1/2×b×5

20=5/2×b

40/5=b (after multiplying with the LHS)

b=8cm

Answer 2

Answer:

before answering the question I must tell u formula :

area = 1/2* b*h

now according to question :-

1. area = 20

h = 5

so

20 = 1/2*b*5

20*2/5 = b

4*2 = b

8= b

2. area = 1/2*b*h

32= 1/2*b*8

32*2/8 = b

4*2 = b

8 = b

3. a = 63

b = 7

a= 1/2*b*h

63 = 1/2*7*h

63*2/7 = h

9*2 =h

18 = h

4. a = 48

b = 8

48 = 1/2*b*h

48= 1/2*8*h

48*2/8 = h

6*2 = h

12= h

5. a = 30

h = 10

30 = 1/2*b*10

30*2/10 = b

3*2 = b

6= b

6. a = 65

b = 5

65 = 1/2*5*h

65*2/5 = h

13*2 = h

26 = h

hope you understand all the questions plz thank my answer
