Answer:
12
Step-by-step explanation:
Answer:
thus next three terms are -3,-5,-7
Step-by-step explanation:
a=1
first find d
-1-1
-2
then a.p= a,a+d,a+2d,a+3d,a+4d
=1,1-2,1+2×-2,1+3×-2,1+4×-2
=1,-1,1-4,1-6,1-8
=1,-1,-3,-5,-7

The area of the given polygon is 1830 cm².
<h3>What is a polygon?</h3>
A polygon is a closed more than two-sided and can be made up of a finite number of straight line segments and is a type of planar figure in geometry.
Each line of the polygonal circuit's segments is referred to as its edges or sides.
We know the area of a square is (side)² and the area of a rectangle is (length×width).
From the given diagram we can think of this polygon as a square having a side length of 46cm and a rectangle having a width (30 - 14) = 16cm and length 21cm, And subtract the area of the rectangle from the area of the square which is,
= (46×46) cm² - (16×21) cm².
= (2166 - 336) cm².
= 1830 cm².
