Answer: B . 48 in²
Step-by-step explanation:
First o all complete the block and find the area
The area of the completed block which looks like a rectangle
= L x B
= 9 x 6
= 54 in²
Step 2 : Find the area of the removed right angled triangle using the formula
= ¹/₂b x h
where the base is 3 in and the height is 4 in
= ¹/₂ x 3 x 4
= 6 in².
Therefore, to find the area of the remaining figure :
Area of the complete block less the area of the right angled triangle
= ( 54 - 6 ) in²
= 48 in²
The option therefore is B
