Answer:
2520cm²
Step-by-step explanation:
Surface area = sum of the area of all the bases.
Area of bottom base = 28 * 30 = 840
Area of right base = 25 * 30 = 750
Area of left base = 17 * 30 = 510
Area of two triangles = ( 15 * 28 ) / 2 = 210 * 2 = 420
Then add all the areas together to find surface area
Surface area = 840 + 750 + 510 + 420 = 2520cm²
Relevant Formulas:
Area of a rectangle = length * width. This formula was used to find the area of the bottom base, the right base and the left base
Area of a triangle = ( height * base length ) / 2 . This formula was used to find the area of the sides which are triangles.
Answer:
It means or stands for the probably that either A or B occurs or both.
Step-by-step explanation:
It really isn't steps to it you just have to learn it.
D over dx (x sin^2(x)) = sin(x) (sin(x) + 2 x cos(x))
Answer with explanation:
The coordinates of four points of Quadrilateral ABCD are
A(4, 5), B(–7, –10), C(–4, –9), D(7, 6)
Slope between two points is given by
As slope of opposite sides are equal and length of Opposite sides are equal.So,the given Quadrilateral is a Parallelogram.
Option A
Yes; The opposite sides are congruent and have the same slope.
