That depends on how many sides the figure has. For example . . . -- If it's a triangle, then its area is 27.7 cm2. -- If it's a square, then its area is 64 cm2. -- If it's a pentagon (5 sides), then its area is 110.1 cm2. -- If it's a hexagon (6 sides), then its area is 166.3 cm2. . . etc.
Triangle area: bh/2 8x8/2=64/2=32(cm2)
45 cm2
56 cm2 * * * * * Only if these are the shorter legs of a right angled triangle and there is no justification for making that assumption. Two sides of a triangle are not sufficient to determine its area.
Sorry the options are actually 64 cm2, 16 cm2, 32 cm2, 50 cm2. Thanks
Area = 1443.376 cm2
Doubling those two dimensions would quadruple the area. So new area = 4*34 cm2 = 136 cm2
Area = 15.58846 cm2
Area = 8.06 cm2.

The area of this triangle is 198 cm2
The area of a 12cm by 5cm right-angled triangle is: 42 cm2
180 cm2
