Dimensions of a painting are 60 cm × 38 cm. Find the area of the
wooden frame of width 6 cm around the painting as shown in Fig.
9.62.
Answers
Answer:
1320 cm²
Step-by-step explanation:
Since we have given the length and breadth of the painting 60 cm and 38 cm respectively.
Area of rectangular painting :
L * B
= 38 * 60
= 2280 cm²
To find the length and breadth of the painting including the frame we'll add the 6cm width to them.
• Length of the Painting + Width of the Frame = Length of the painting including frame.
= 60 + 6 + 6
( you can get it by the attachment )
= 72 cm
• Breadth of the Painting + Width of the Frame = Breadth of the painting including frame.
= 38 + (6)2
= 50 cm
Area of the rectangular painting including the frame:
L * B
= 72 * 50
= 3600 cm²
Area of Painting including frame - Area of Painting only = Area of frame
= 3600 cm² - 2280 cm²
= 1320 cm²
By using area of rectangle = l × b
= 60 × 38
= 2280
answer = 2280 sq.cm
28 + 6= 34 cm
area of rectangle = l × b
= 66× 34
area of frame including painting = 2508 sq.cm
=2508 - 2280
= 228 sq.cm
area which is between inner dimensions and outer dimensions = 228 sq.cm
