answer it.please it is my biggest question.​

Answer 1

Answer:

882 sq cm.

Step-by-step explanation:

The breadth of the rectangle is 90cm., which makes the two sides each of the vertical shaded rectangles.

The area of these 2 boxes would be length × breadth =

2×(3×90)=540 sq cm.[3×90 for each box]

The length of the rectangle is 120cm., which makes the two sides of the horizontal shaded rectangle.

The area of this box would be length×breadth= 120×3 =360 sqcm.

But there are 2 overlapping square areas of side 3cm in the junction of the vertical and horizontal boxes.The area of each of these boxes = 3×3 =9sq cm.

There are 2 of them,so, 2× 9 = 18 sq cm.

Therefore,the actual area = 540 + 360 - 18 = 882 sq cm.

If you understood,please mark it as thhe brainliest one.

Thank You!
