Answer:
4,257 m²
Step-by-step explanation:
step 1
Find the lateral area of the rectangular prism (ottoman)
The lateral area is
LA=PH
where
P is the perimeter of the base
H is the height of the prism
Find the perimeter of the base P
P=2(37+21)=116 cm
we have H=30 cm
<em>Find the lateral area</em>
LA=116(30)=3,480 m²
step 2
Find the area of the top of the ottoman
B=37*21=777 m²
step 3
we know that
The fabric needed to cover the sides and top of the ottoman is equal to sum the lateral area plus the area of the top
3,480+777=4,257 m²
The different colours that has been used is red, yellow and blue and the number of central squares is = 73 boxes
<h3>The Mondrian's work</h3>
The First division that was divided into 9 equal parts has = 1 coloured red.
The second division is 8 remaining
uncoloured squares into 9 equal squares = 8×9= 72boxes
The number of boxes that was coloured yellow =8 boxes
The remaining uncolored boxes which is = 72 - 8 = 64 boxes
The third division is the division of each remaining uncolored boxes into 9. That is 64 × 9 = 576
The number of boxes that was coloured blue = 64 boxes
Therefore the number of central squares that has been coloured = 1 + 8 + 64
= 73 boxes
