Question

can anyone
solve it .....
please​

Answer 1

Answer:

Lateral surface area + twice of base area gives the total surface area.

TSA = 40 & LSA = 26. Therefore, twice is base area is their difference i.e., 14.

Hence, base area is 7m^2.

Answer 2

Step-by-step explanation:

2(lb+bh+hl)=40

(lb+hl+bh)=20. 1eq.

2(lh+bh)=26

(lh+bh) =13. 2eq.

from solving eq. 1 and 2

lb+13=20

lb=7m sq.

area of it's Base is 7m sq.
