Question

The following diagram represents a painting
fitted with a 4 cm wide wooden frame around
it. Find the area of the frame.​

Answer 1

Answer:

284cm^2

Step-by-step explanation:

ar of frame = total area - area of photo

= 60×40 - 56×36 = 2400-2016 = 284

Answer 2

Answer:

736cm^2

Step-by-step explanation:

divide the frame in two rectangles

1)length=56/ breadth=4(width)}cm×2

2)length=36/bredth=4}cm×2

area of rectangle=length×breadth

so, 1)56×4=224cm but we have 2 rectangles like it

so, 224×2=448cm

now 2)36×4=144cm

but we two rectangles like it so, 144×2=288cm

now add both area and you will get the area of whole frame which is 288 (rectangle 2)+448 (rectangle 1)=736 cm^2
