It is 23 square metres.
Formula: S=1/2 bh S - area, b - base, h - height S= 1/2 * 11* 23= 126.5
18 + 8 + 4 = 23
Area of rectangle: 58*23 = 1334 square m
sqrt(289) m = 17 m
Area of room: 120 times 17 = 2040 square m
It is 23 square metres.
Square root 529 which is 23 m
Formula: S=1/2 bh S - area, b - base, h - height S= 1/2 * 11* 23= 126.5
18 + 8 + 4 = 23
30 - 2 = 28 .25 - 2 = 23 .28 * 23 = 644Answer The area covered by grass is 644 square meters
23+17 is 40.
Area of rectangle: 58*23 = 1334 square m
sqrt(289) m = 17 m
Just multiply them. Eg Length 17, width 23 is an area of 17 x 23 ie 391 squft
I am taking this to mean area of 69x17 m rectangle. 1173m2
It is M-23.
