A rectangular picture 6cm by 8cm is enclosed by a frame \(\frac{1}{2}\)cm wide. Calculate the area of the frame
A
15sq.cm
B
20sq.cm
C
13sq.cm
D
16sq.cm
E
17sq.cm
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
Area of the rectangular picture = L x B = 8 x 6
= 48 sq.cm.
Area of the whole surface (which is gotten by adding \(\frac{1}{2}\) on every side to the original picture size) is 9 x 7 = 63 sq. cm
area of the frame is 63 - 48
= 15 sq. cm
