The shape is formed from a rectangle measuring 13cm by 25cm from with a rectangle 6.3cm has been cut out.

60 cm

Step-by-step explanation:

perimeter of big rectangle- 13+13+25+25=76cm

perimeter of smaller rectangle- need to find the width so do 14.6+8.7=23.3

25-23.3=1.7

width of smaller rectangle=1.7

perimeter of smaller rectangle= 1.7+1.7+6.3+6.3=16

Perimeter of the shape= 76-16=60 cm

answer: 177/8

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
