If the shape is a triangle, then the area is approx 8.2 sq in.
20 1/8
184
Surface area = 2*(L*B + B*H + H*L) = 2*(4*5 + 5*8 + 8*4) = 2*(20 + 40 + 32) = 2*92 = 184 m2
Example length 5cm and height 4cm Area is length times height = 5 x 4 = 20cm Perimeter is length top and bottom = 5 + 5 = 10 plus height left and right = 4 + 4 = 8 making total 10 + 8 = 8 or (5 + 4) x 2 = 18cm
20cm squared
4/5 * 5/8 = 4/8 = 1/2 or 0.5
4(-5+7)+8(-8+5)4(+2)+8(-3)8+8(-3)8+-24-16
4/8 and 5/8 is .5 and .625, respectively. If you mean (4+5)/8, the answer to THAT is 1.125.
8/(4/5)=8/.8=10or 8/(4/5)=8*(5/4)=40/4=10
5/8 + 5/8 = 10/8 = 5/4 or 11/4
5/8 + 13/4 = 5/8 + 7/4 = 5/8 + 14/8 = 19/8 = 23/8
