Question

Please solve it's urgent ​

Answer 1

Step-by-step explanation:

l=5+5=10

b=5

p=2×(l+b)

2×(10+5)

2×15

30

a=30

area of triangle=1/2xbasexheight

b=5 h=2.5

1/2×5×2.5

6.25

B)=7.25

Answer 2

Answer:

Step-by-step explanation:

(A) Perimeter of rectangle =2(l+b)

1st double the length 5+5=10

So length =10cm

Perimeter =2(5+10)

Perimeter =10+20

Perimeter =30cm

(B) Area of triangle =1/2mulitply base multiply height

Area of triangle =1/2 multiply base multiply 5

Area of triangle =5/2

Area of triangle =2.5cm square
