Option a 26 inches square
Step-by-step explanation:
Given in the picture is a triangle with 3 sides as 10.8 inches, 5 inches and base =10+3 = 13 inches
The altitude for base 13 inches is shown as 4 inches.
We know that for any triangle area
=1/2 * base * height
Here base = 13 and height = 4
Hence area = 1/2 (13)(4) = 26 inches square
Answer is option a
---
This can be done in another way also
There are two triangles one with base 10 inches and height 3 inches and another with base 3 inches and height 4 inches
Area of combined figure = sum of area of two triangles
= 1/2 (10)(4) +1/2(3)(4) =
20+6
=26 square inches
