Step-by-step explanation:

Let's start by finding the area of figure 1

The square:

15cm×15cm=225cm²

Then we're going to find the area of figure 2

it's a rectangle (A=L×W)

L=60cm-15cm(because those cm have been cut off)=45cm

W=40cm

Area=45cm×40cm

=1800cm²

Then we add up the sum

Area of 1+Area of 2

=225cm²+1800cm²

=2025cm²

Answer:

140 cm is the perimeter of the unshaded shape.

Step-by-step explanation:

Perimeter of the rectangle in whole = 2l + 2w

Where length is 60 cm and width is 40 cm.

P = 2 × 60 + 2 × 40

= 120 + 80

= 200 cm

To find the perimeter of the unshaded square = 4l

Where the length is 15 cm.

P = 4× 15

= 60 cm

To find the perimeter of the shaded shape = Perimeter of rectangle - Perimeter of unshaded square.

P = 200 - 60

= 140 cm

140 cm is the perimeter of the unshaded shape.
