you are wrong go look in atext book no cheating on computers!
Area of the circle: pi*7squared=153.93804 square cm
4 * 7=28 28/2=14 sq cm
56 cm 2 * * * * * 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.
A triangle with side a: 7, side b: 7, and side c: 5 cm has an area of 16.35 square cm..
77cm. That should've been quite obvious.... all you do is multiply 7 by 11 and BAM, you have 77!
1/2*5*7=17.5 square cm * * * * * 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 t…riangle are not sufficient to determine its area.
area=7cm x 7cm=49cm^2
Two sides of a triangle are not sufficient to determine its area.
7 cm * 4 cm * 3 cm=7 * 4 * 3 * cm * cm * cm=84 cm 3
Since there are 4 lengths given, the shape could be a quadrilateral. Unfortunately, the lengths of the sides is not enough information to determine the shape of a quadrilatera…l. As an illustration, consider a square of sides 10 cm. Its area is 100 cm 2 . But it can be "distorted" into a rhombus with the same sides but the area can be reduced to as close to 0 as you like. Four linear measures could also mean that it is a 4-dimensional cuboid in hyperspace or some other shape in 2 or 3 dimensions. But since these shapes cannot be determined, it is not possible to find an answer to the question.
It depends on whether you want the width as a fraction of the length or perimeter or something else - like the diagonal.
