By Pythagoras, the length of the diagonal = sqrt[(1.8)2 + (1.2)2]
= sqrt[3.24 + 1.44] = sqrt[4.68] = 2.16 m
The area of rectangle is : 96.0
36 m
Assuming that the measures given in the question refer to the lengths of the sides of the rectangle, the answer is 40 metres.
Perimeter = 12+12+3+3 = 30m
Perimeter=2(l+b) =2*6 =12m
There cannot be a 12m rectangle. A rectangle is a two dimensional object and so there must be two linear measures to describe it. Either there is measure of another length, for example a 12m x 8m rectangle. In that case the question is redundant. Or the 12m is intended as a measure of area and should actually have been 12 SQUARE metres. However, in that case, there are infinitely many possible solutions.
The area of rectangle is : 96.0
i think that it si 4x3 and it eqals 12
36 m
Assuming that the measures given in the question refer to the lengths of the sides of the rectangle, the answer is 40 metres.
If you mean area of a rectangle then it is 25 times 12 = 300 square m
12m
Perimeter is 36 mArea is 72 square m
Area = 12*8 = 96 square m
it is 12m long
Perimeter = 12+12+3+3 = 30m
if the perimeter is 12 then the semi perimeter is 6 p=2L+2w 12=2L+2w by division 6=L+w
